Sebelumnya kita sudah bahas tentang cara menambahkan marker pada google map. Sekarang masih menggunakan peta sebelumnya kita akan tambahkan polyline atau garis pada google map. Garis ini nantinya bisa berfungsi sebagai bentuk jalan, jalur atau pembatas. Caranya dengan membahkan kode dibawah ini
var jalan = [
new google.maps.LatLng(-2.124938, 101.434392),
new google.maps.LatLng(-2.142178, 101.440056),
new google.maps.LatLng(-2.145952, 101.441344)
];
var bentukjalan = new google.maps.Polyline({
path: jalan,
geodesic: true,
strokeColor: '#FF0000',
strokeOpacity: 1.0,
strokeWeight: 2
});
bentukjalan.setMap(map);
Sehingga keseluruhan kode google map kita menjadi seperti ini:
<!DOCTYPE html>

function initialize() {
var myLatlng = new google.maps.LatLng(-2.1788761,101.4415862);
var mapOptions = {

}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
//marker baru
var latlng2 = new google.maps.LatLng(-2.1248409,101.4273383);

'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString, maxWidth: 400
});
var marker = new google.maps.Marker({
position: latlng2,
map: map,
title: 'tes'
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
var jalan = [
new google.maps.LatLng(-2.124938, 101.434392),
new google.maps.LatLng(-2.142178, 101.440056),

var bentukjalan = new google.maps.Polyline({

google.maps.event.addDomListener(window, 'load', initialize);

gan gimana kalau membuat polyline beda warna, misal ada 3 titik, titik 1-2 polylinenya warna Merah, dari titik 2-3 polylinenya warna hitam.
